Overview
On ultrasound metastasis to liver and fluid in the peritoneal cavity can be identified.
Ultrasound
- The ultrasound procedure may use an external or internal device, or both types:
- Transabdominal ultrasound:Abdominal ultrasound is less sensitive and will miss small tumors, but can identify cancers that have spread to the liver and build-up of fluid in the peritoneal cavity (ascites).It may be used for a quick and cheap first examination before other techniques.
- EUS (Endoscopic ultrasound): The doctor passes a thin, lighted tube (endoscope) through the patient's mouth and stomach, down into the first part of the small intestine. At the tip of the endoscope is an ultrasound device. The doctor slowly withdraws the endoscope from the intestine toward the stomach to make images of the pancreas and surrounding organs and tissues.
- Findings are non-specific and include:
- Generally hypoechoic mass
- Double duct sign may be seen
